Rust Preventatives
The Nanoplas family of rust preventatives is one of our truly unique product lines, because it goes on completely “dry”. Our reasoning was simple; to reduce scrap and downtime spent cleaning the mold prior to start up. For these reasons we developed our four dry film rust preventatives Mold Guard, Mold Guard Green, The Defender, and Safe-T-Guard to help overcome these problems and allow you to start production immediately without setbacks.
Mold Guard™
Mold Guard™ is a truly dry rust preventative. It’s moisture displacing chemistry provides a guard for your mold that will not allow corrosion to penetrate.
Mold Guard Green™
Mold Guard Green™ is a truly dry rust preventative. It’s moisture displacing chemistry provides a guard for your mold that will not allow corrosion to penetrate. Green tint added for better visibility on the mold.
Safe-T-Guard™
Safe-T-Guard’s™ moisture chemistry provides a guard for your machine that will not allow corrosion to penetrate. The guarding properties provide excellent film strength, and since it goes on dry will not break down grease and other lubricants that are already present on the surface.
The Defender™
The Defender™ is a semi-dry, dual purpose rust preventative. It’s semi-dry properties allow for longer lasting protection without causing bleed through. It’s acid vapor neutralizer additive protects against PVC and other corrosive materials. The addition of a green dye indicator helps show the coverage while avoiding over spray on the mold.
The Defender™ No Dye
The Defender ND is a semi-dry, dual purpose rust preventative. Its semi-dry properties allow for the longer-lasting protection without causing bleeding through. The acid vapor neutralizer additive protects against PVC, other corrosive materials, and fingerprints. Its clear film provides easy removal before start-up. The film can be molded through on the first few shots. For longer-term application, apply two coats.
The Protector™
The Protector™ is a semi dry, dual purpose rust preventative designed to be used on both cold and warm molds. Its semi dry nature allows for longer lasting protection without causing bleed through. The acid vapor neutralizer additive protects against PVC and other corrosive materials.
Key Benefits of Rust Prevention Spray
Our rust prevention spray is engineered specifically for injection molding tooling and coatings, providing superior corrosion resistance in demanding production environments. Designed to protect precision molds from rust during downtime, storage, or shipping, it creates a micro-thin barrier that won’t interfere with mold performance or part finish.
By preventing rust, you not only extend the lifespan of expensive tooling but also maintain surface integrity for consistent, defect-free production runs. This specialized rust protection spray reduces maintenance needs, shortens cleanup times, and keeps molds ready for immediate use.
How Our Rust Protection Spray Works
The spray’s advanced anti-corrosion agents bond tightly to metal mold surfaces, sealing out humidity, condensation, and airborne contaminants commonly found in production facilities. Its dry-film formula prevents oily residue buildup and some of our products can be molded through at start up.
Once applied, the coating resists breakdown during long-term storage and easily wipes or flushes away before production resumes. The result is reliable rust protection without the risk of surface pitting, dimensional changes, or part contamination.
Use Cases & Applications for Rust Prevention Spray
Our rust prevention spray is ideal for:
- Protecting injection molding tools during seasonal or long-term storage
- Preventing corrosion between production cycles in humid or temperature-fluctuating environments
- Shielding molds during overseas or overland shipment
- Maintaining cavity and core surface quality for high-precision applications
- Protecting auxiliary equipment such as ejector pins, platens, and mold bases
FAQs
Does Rust Protection Spray Work?
Yes. When formulated for injection molding applications, rust protection spray is highly effective at preventing corrosion on mold surfaces during storage, shipping, and downtime. It works by creating a thin, moisture-resistant barrier that blocks humidity, condensation, and airborne contaminants from reaching the metal.
Does Rust Protection Spray Affect Mold Surface Finish?
No. This injection mold-specific rust protection spray is formulated to create a thin, even layer that will not etch, stain, or alter mold surface textures. It’s easily removed before production to ensure part quality remains consistent.
Can I Apply It Without Disassembling the Mold?
Yes. The aerosol delivery allows precise application to cavities, cores, and moving parts without full disassembly, saving valuable maintenance time.
Better Together
When used in tandem, Nanoplas products can help you significantly reduce costs, downtime, scrap, and more. Scientifically formulated, each product is individually effective, so when used together, they enhance mold performance significantly.
